Direct Measurement of Helicoid Surface States in RhSi using Nonlinear Optics
Dylan Rees, Baozhu Lu, Yue Sun +6
Despite the fundamental nature of the edge state in topological physics, direct measurement of electronic and optical properties of the Fermi arcs of topological semimetals has pos…
Suppression of second-harmonic generation from linear bands in the topological multifold semimetal RhSi
Baozhu Lu, Sharareh Sayyad, Miguel Ángel Sánchez-MartÍnez +4
Recent experiments in the topological Weyl semimetal TaAs have observed record-breaking second-harmonic generation, a non-linear optical response at generated by an incoming l…
Incommensurate magnetism mediated by Weyl fermions in NdAlSi
Jonathan Gaudet, Hung-Yu Yang, Santu Baidya +11
Emergent relativistic quasiparticles in Weyl semimetals are the source of exotic electronic properties such as surface Fermi arcs, the anomalous Hall effect, and negative magnetore…
A new noncollinear ferromagnetic Weyl semimetal with anisotropic anomalous Hall effect
Hung-Yu Yang, Bahadur Singh, Jonathan Gaudet +18
A developing frontier in condensed matter physics is the emergence of novel electromagnetic responses, such as topological and anomalous Hall effect (AHE), in ferromagnetic Weyl se…
Transition from Intrinsic to Extrinsic Anomalous Hall Effect in the Ferromagnetic Weyl Semimetal PrAlGeSi
Hung-Yu Yang, Bahadur Singh, Baozhu Lu +10
Recent reports of a large anomalous Hall effect (AHE) in ferromagnetic Weyl semimetals (FM WSM) have led to a resurgence of interest in this enigmatic phenomenon. However, due to a…
Observation of Topological Photocurrents in the Chiral Weyl Semimetal RhSi
Dylan Rees, Kaustuv Manna, Baozhu Lu +6
Weyl semimetals are crystals in which electron bands cross at isolated points in momentum space. Associated with each crossing point (or Weyl node) is an integer topological invari…
Fast Reflective Optic-Based Rotational Anisotropy Nonlinear Harmonic Generation Spectrometer
Baozhu Lu, Jason D. Tran, Darius H. Torchinsky
We present a novel Rotational Anisotropy Nonlinear Harmonic Generation (RA-NHG) apparatus based primarily upon reflective optics. The data acquisition scheme used here allows for f…
Fourier Domain Rotational Anisotropy Second Harmonic Generation
Baozhu Lu, Darius H. Torchinsky
We describe a novel scheme of detecting rotational anisotropy second harmonic generation (RA-SHG) signals using a lock-in amplifier referenced to a fast scanning RA-SHG apparatus.…
Resonance-enhanced optical nonlinearity in the Weyl semimetal TaAs
Shreyas Patankar, Liang Wu, Baozhu Lu +10
While all media can exhibit first-order conductivity describing current linearly proportional to electric field, , the second-order conductivity, , relating current to…
